Abstract:
This study aims to determine the impact of several pre-planting weed control methods on the
diversity of plant parasitic nematode species and their population levels in the rhizosphere of corn crops.The
research was conducted from March to June 2024. On farmer's land in Binuang, Tapin Regency. The land
observed is land No tillage + glyphosate, No tillage +sulphosate, Minimal tillage (on tractor), Minimal
tillage (on tractor) + Oxadiazon, Minimal tillage (on tractor) + Butachlor, Conventional tillage (hoeing),
Control (natural / no tillage).Observations based on the results of soil samples taken when the corn crop
was harvested. The soil samples wereExtraction using a modified Baerman funnel (Dropkin 1991). Results
of extraction of parasitic nematodes found identified based on morphological characteristics up to
genus.Identification of nematodes refers to the books: Pictorial Key to Genera of Plant Parasitic Nematodes
(Maiet al.1975). The results of research on the impact of pre-planting weed control on nematode diversity
from corn rhizosphere samples found 16 nematode genera, Criconemella, Ditylenchus, Hemicycliophora,
Hemicycl, Heterodera, Hirschmanniella, Longidorus, Meloidogyne, Paratylenchus, Pratylenchus,
Psilenchus, Rotylenchus, Trichodorus, Tylenchorhynchus, Tylenchulus, Tylenchus, and there are variations
in the genus and population of nematodes in each soil sample.
